Hi,
I am currently reviewing the design of a tube sheet for a boiler that is made from stainless steel and has stainless steel piping welded to it. This falls in line with subsection HG-346 of Section IV of Asme which allows me to calculate the required thickness of the plate, which I have calculated at approx .35. My main consideration is to try and reduce the over all thickness of the plate further by adding in flat stays to the back of the unit that would be welded in place. These would be flat sheet metal as well as a cylindrical piece for the center.
What I am unsure of is how to go about assessing the part once these have been added in. I have attached two drawings of the parts, one without any additional stays and the other with proposed stays added. Any ideas on the best way of approaching this problem? The design pressure of the system is 160psi.
Let me know if I have left out any details.
Thanks
